Effect of Colchicine Concentration and Exposure Duration on the Growth and Flowering of Petunia hybrid L.

“…These are in line with what Majdi and Karim zadeh [14], found to have increased vegetative growth indicators compared to normal plants outside the effect of colchicine. It agrees with the results of [15], which indicated a significant superiority in the length of germination and flower stem in a study of the effect of the mutagenic substance colchicine on carnation. Table 1.…”

“…The results show that the increased concentration of colchicine and the duration of spraying It led to an increase in the number of days until flowering, and this is consistent with [16], that the increase in the number of flowers came as a result of treatment with a high concentration of colchicine accompanied by prolonged spraying, and this is consistent with the results of other studies, including what was done by [17]. The increase in flower diameter as a result of treatment with colchicine at a concentration of 0.5 mg L -1 may be due to an increase in water in the tissues, and this is consistent with [18], and perhaps as a result of an increase in chloroplast in the guard cells, and that the coordination life of the flowers was longer in concentration than the comparison treatment This is due to physiological reasons for flowers, as colchicine stimulates the formation of the anti-ethylene enzyme, which causes the aging of flowers and the end of their coordination life, in addition to the increase in the size of flower petals in plants under the influence of colchicine, which increases their nutritional stock and increases the duration of their survival in coordination [19], and it agrees with the results of [20],…”
